I would ask @Jay Hemdal and @vetteguy53081 how best to establish a tank for sharks. My understanding is that they need a very mature biofilter, so this would likely be a long-term plan, adding the sharks at the end when the tank was ready.

Good luck!

Doing this can be challenging and costly and you want to do everything to keep nitrates down. I recommend no less that 300 gals preferably oval shaped and well equipped with a UV unit, denitrator, oversized skimmer and good flow. You also want to maintain salinity with steady readings and feeding will be a challenge as most sharks eat messy foods which raise nitrates. I recoomend sharks such as epaulette, cat sharks and bamboo sharks which are less difficult to maintain.
Plans on weekly water changes of at least 20% to maintain prime conditions

There are choices. Mine are Tangs, but be prepared with any species to maintain health and have a quarantine setup ready in case needed. This can be a pricey hobby, have a plan before you start this journey
